SPECIFICATION forming part of Letters Patent No. 414,869, dated November12, 1889.

Application filed June 29, 1889. Serial N0.316,0'79 (No model.)

To all whom it may concern.-

Be it known that I, GEORGE TV. MCELHONE, a citizen of the United States,residing at Binghamton, in the county of Broome and State of New York,have invented certain new and useful Improvements in Printing Presses;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

Similarletters refer to si milarparts thro u ghout the several views.

My invention is an improvement in printing-presses for printing uponthick stiff sheets, and is designed more especially for printing uponcigar-boxes, the printing being done after the boX is out and before itis nailed up.

The invention consists in the arrangement and combination of the severaldevices, by which the boards are fed regularly to the press, a uniformimpression is secured, and the press is made substantially automatic inits operation.

In the accompanying drawings, Figure 1 is a perspective of my improvedpress, the end of the frame and-also the end of the pitman being brokenoff, as they contain nothing new, the same driving mechanism beingemployed as in the ordinary presses. Fig. 2 is a longitudinal verticalsection showing the construction of the bed-plate B and also theposition of the several parts when the board is passing under thepressure-roller, where it receives the impression. section of one of thefingers f which drive -the board through. Fig. 4 is a detail of a partof one side of the press, showing the gage for holding the differentwidths of boards, with its means of adjustment. Fig. 5 is a verticalcross-section cut on two different lines, the right-hand side being cutthrough the head or face-plate of the bed, and the Fig. 3 is a crosspiece, though any of the ordinary forms of frame may be used. At theupper inside it is fitted with a slideway for the bed-plate B to travelin, as shown most clearly in the cross-section at Fig. 5. Over thisslideway are the plates at a to hold the bed down to place, and theserun forward to the gageplates G, a little forward of the ink-roller I,and are bolted down upon the frame. tween these plates a a and thepressureroller R are the gage-plates G, of which one is shown clearly inFig. at, which also cover the slideway, and are held down upon the frameby bolts passing through slots in the tached to the front gage is shownin outline in Fig. 4 and in dotted lines in Fig. 1. Across the machineand fastened to the frame is another upright g, which must be set justfar enough above the slotted springs H H to allow a single board to bedriven through under it. Attached to the block which carries thepressure-roller is the slotted adjustable arm e, which runs outside andaround the front upright and across the machine to hold the boards fromthat direction, and maybe moved back and forth on the bolts to fit it tothe lengthof board to be printed to hold them closely against theupright g. It will be noticed that it has a lip extending down betweenthe slotted springs to prevent the un- 0 der board being drawn back bythe bed upon its return.

Mounted in the slideways of the frame and fitted to run easily thereinis the bed-plate 13.

This is driven by the pitman P, which is attached to the bed at theunder side by the lug B and any form of attachment may be used. crankmotion, either by a band-wheel and crank-shaft on the frame of themachine, or I00 from other source, as most convenient. Bolted on eachside of the lug B are the arms S S,

These are moved out 70 The pitman is driven by the ordinary which extenddown and outward beyond the frame and carry the shoes S S. Fitted in theface of the bed-plate is an ink-disk d, Fig. 1, which is attached to.aratchet or similar device to make a partial revolution at each journeyof the bed-plate, the same as the ow dinary press, and on this disk theink is spread, which is used in the process. Set in the face of thebed-plate is a small dog 0', the use of which will be explained furtheron. I11 front of this the bed-plate is cut down to form the type-bed 3',in which the form is set. The toe of the bed 15 comes up nearly to theline of the face of the bed-plate to forma support for the type-form,and also serves to draw back the fingers f f, which drive the boardsthrough the press.

Across the frame is an ink-roller I, set low enough that it reaches thetype when they go under it, and also pressing the ink-disk when itpasses back and forth. The roller is mounted in boxes having stems f i,which go down through the frame and through lugs on the outside of theframe. Near the lower end of the stem a pin is put through, and betweenthis and the lugis a coiled spring to hold the roller down, except whenit is raised by the shoe, as noted further on.

Seated and riveted in the inner sides of the gage-plates G G are theslotted springs H II, which need to be made of steel, and which are leftfree beyond the gage-plates, and are extended beyond the end of theframe. Mounted in the slots of these spring-plates are the fingers ff,of which a cross-section is shown in Fig. These are deep enough belowthe springs, that they are driven forward by the face of the bed and aredrawn back by the toe of it when it returns. The dog 6 needs to projectjust as far forward of the plate as the length of these fingers, so thatthey are in line when they reach the board.

A heavy prcssurea'oller It is at the end of the frame, and is carried inadjustable boxes, as shown in Fig. 4., so that it may be raised orlowered, as a greater or less pressure upon the type is desired. A typeof hardened steel may be used without ink, if desired, and the lettersout into the board.

The method of operation of the press can be readily understood, and isas follows: The type are set and the form adjusted so as to printbetween the spring-plates H H. The boards to be printed are piled inflat on these plates, and the gages and uprights are adjust-ed so as tohold them substantially close but not tight. \Vhen the press is startedand the bed moves forward, the shoes S S, as they pass under the stemsof the ink-roller boxes, raise them up at the moment that the dog e goesunder the roller; but at all the rest of the stroke the roller is helddown firmly by the springs on the stems 1i '1', and the type are inkedby the roller. This in turn is inked from the ink-disk, upon which theink is spread. \Vhen the face of the bed-plate comes forward, so that itcatches the fingers f j, which are withdrawn beyond the boards, theseand the dog 6, as they are driven forward, catch the lower board of thepile and drive it forward on the spring-plates under the pressure-rollerR. The roller bears the board down upon the type, the springs yieldin gsufficiently to admit of a good impression, and the board is carried outbeyond the roller. The bed has then reached the limit of its stroke, andwhen it returns, the toe of the bed B catches the fingers ff and takesthem back to their starting-point. It will be noticed that the back endof these fingers is cutaway substantially to the level of the springs,thus forming a wedge, which raises the under boards as they are drawnback under the pile. As they go out, the boards dropidown on thesprings, ready for the next stroke.

Having thus described my invention and the method of its constructionand operation,

what I claim as new, and desire to secure by Letters Patent, is 1 1. Ina board-printing press having a fixed frame and 1011 gitudinally-movi ng bed, the adj ustable gages G, with uprights g in combination with flatslotted spring-plates ll, adjustable with the gages, said spring-plateshaving fingers f f to catch the boards and drive them through .under thepressure-roller, where they are borne down upon. the type and thenforced out of the press, all substantially as shown and described.

2. In a printing-press of the kind described, the bed-plate B, with itstype-bed B,ink-disk d, and an ink-roller I, in combination with thespring-plates II II to support the boards, said spring plates havingsliding fingers driven by the bed-plate to catch the boards and carrythem forward "under the pressureroller, where they are borne down uponthe type and receive the impression, all substantially as shown anddescribed.
